Yes, it is finally here, Facebook stock has fallen below the $28 per share price many investors have been waiting for. Still, more pessimists are saying they’ll wait for it to fall to $10, but I suspect those days won’t arrive. Currently shares of Facebook are trading at $27.20, but they are rapidly falling as I write this.

You might recall that Facebook shares started out at $38 and reached a high of $45 the opening day of the IPO back on May 18th. Since then however, they have been on a steady decline, with a short stabilization around $32 last week. Today marks a new low for Facebook and its underwriters as they work to clean up the fallout from what can only be called, a disastrous initial public offering.

While some investors might be turned off by the less than stellar performance of the shares, others are certain Facebook is still a good investment and there is evidence to show they will overcome the challenges that lie ahead of them. Speaking directly to their shortcomings with mobile advertising, Facebook has added new features that will allow advertisers to create and distribute mobile ads in standard and rich media formats. They have also given advertisers access to tools that will allow them to easily track and analyze ad performance.

Also, Facebook has continued with plans to expand services and advertising efforts into new countries with hopes of inspiring connectivity in a broader spectrum of nations. The company opened a new office in Dubai yesterday and have already experienced advertising interest in the Middle East and North Africa.

Regardless of what your views on the longevity of the social networking site are, you cannot deny their persistence and fortitude with meeting business challenges head on. So while we may see the prices of Facebook stock continue to fall, I doubt we’ll see a time when they are considered worthless. Remember, Facebook isn’t a company that pays dividends, so many of the factors which play into the pricing are driven by perception and depend on psychological factors stemming from investors and the investment environment.
